Been using Vimium for years too and it's great, but it's really not the same. The late, great Vimperator extension was more comparable to QuteBrowser but it stopped functioning (on Firefox) when they switched from XUL to web extensions.
Vimium mainly gives you keyboard navigation, but QuteBrowser removes the address, tab and bookmark bars and instead gives you keyboard access to everything via the very Vim-like status bar at the bottom. Incidentally this also frees up quite a bit of vertical screen real estate, which is a big deal to me. Browser settings, scripts, etc. are also all accessible via the keyboard — Vim style.
Edit: The lack of a solid Bitwarden integration in QuteBrowser is kind of hurting though.
